Step-by-step explanation:
The variables in this experiment are:
- Independent variable: A. Small ball, B. Large ball, C. Feather
- Dependent variable: None of the above
In this experiment, the size of the ball (small or large) and the material (feather) are the independent variables, while the dependent variable is not specified. The dependent variable is the variable that is measured or observed in response to changes in the independent variable.
